Gov. Jerry Brown, hoping to give a jolt to the electric vehicle industry, signed six bills Saturday to encourage drivers to buy electric cars.

The bills take several approaches, from extending existing sticker programs that allow vehicles meeting certain low-emission standards, including electric cars, access to carpool lanes to making it easier for drivers to use charging stations and requiring their inclusion in new developments.

He signed the bills on National Plug In Day, a celebration of all-electric and hybrid-electric vehicles.

The bills the governor signed into law:

-- Extend until 2019 the white-sticker program that permits pure zero-emission vehicles - 100 percent battery electric, hydrogen fuel cell and compressed natural gas - to use carpool lanes, regardless of the number of occupants.

-- Extend until 2019 the green-sticker program that allows up to 40,000 advanced-technology low-emission vehicles to use carpool lanes. Qualifying vehicles include superclean plug-in hybrids and possibly some hydrogen-fueled internal combustion engines.

-- Make charging stations open to all electric-vehicle drivers, as well as easier to locate and simpler to use.

-- Require state housing and building standards agencies to develop standards for including electric-vehicle charging infrastructure in multifamily housing and nonresidential developments.

-- Extend until 2024 several programs that intend to reduce automobile emissions by supporting low-emission vehicle technology development and modernization.

California is already a leader in electric vehicles with roughly 35 percent of the nation's plug-in vehicles, according to a 2012 study by the California Center for Sustainable Energy and the California Air Resources Board. The state's efforts to lead a surge in the number of electric vehicles on the road include an executive order signed by Brown that sets a target of 1.5 million zero-emission vehicles in the state by 2025.

State Sen. Leland Yee, D-San Francisco, who wrote the green-sticker extension bill, said in a statement that the bills will help California expand its population of green vehicles.

"Embracing technological advances will help reduce our carbon footprint while creating jobs," he said. "I thank Gov. Brown for keeping us ahead of the curve."
